My Welsummer, Nancy, is 18 weeks old and all of a sudden has started making a strange squawking sound when she is around me. I have 5 other hens, each one a different breed, and I've gotten to know each hen's habits and behaviors. None of them have started laying yet and I wonder if Nancy's behavior of making a loud squawking noise only when I'm outside is a way of her telling me something is unusual. I've examined her and can't find any injuries. What could be going on?
